Kimya, the Additive Manufacturing materials subsidiary of French printing and coating firmARMOR, has recently concluded that using recycled PETG filaments can significantly reduce CO2 emissions. KIMYA’s recently published Life Cycle Analyses (LCA) for its 3D PETG filaments indicates that recycled PETG filaments help to reduce CO2 emissions by up to 35%, compared to their non-recycled counterparts.
Kimyaconducted the LCA in conjunction with绿色, a Paris-based accounting platform designed to reduce the carbon emissions of its users. Based on France’s Environment and Energy Management Agency (ADEME) guidelines, it is hoped that these findings will encourage users to favor recycled filaments over less sustainable alternatives.
“Born out of our company’s DNA and a strong demand from our distributors, the Life Cycle Analysis, carried out on our standard and recycled PETG filaments, makes it possible to provide users with transparent information on the environmental impact of the materials they use, in order to encourage them to choose more environmentally friendly alternative”, said Benoît Stoeux, Managing Director at KIMYA. “Our LCA approach is part of our ongoing commitment to more sustainable production as evidenced by our “Remake” line of recycled filaments that we are continuing to expand to meet everyone’s needs”.
Moreover, Annabelle Guillet, Director of Societal Innovation at ARMOR, commented, “we at ARMOR GROUP act according to a clear strategic line, respectful of the environment and giving a central place to the women and men of the company, as evidenced by our EcoVadis gold medal”. Ultimately, Guillet characterizes ARMOR’s collective vision as “investing for the future”, with environmental sustainability being key to this.

LCA衡量产品一生的环境影响，涵盖原材料，生产和使用的提取。Kimya对其回收和标准PETG 3D丝进行了LCA测试。最终的数据表明，回收的细丝排放了4.08 kgco2，而标准的PETG细丝产生了6.27 kgco2的排放。这35％的差异强调了回收产品所提供的环境效益，Kimya渴望强调消费者。
KIMYA对环境可持续性的关注压力tches beyond the use of recycled 3D filaments. Indeed, Stoeux has highlighted that their packaging is now “100% environmentally friendly”, utilizing soluble ink and recycled cardboard. Moreover, the mounting flanges for KIMYA’s 3D filament spools are slated as now consisting of 95% recycled polycarbonate. Looking to the future, Stoeux indicates that the company is seeking to “conduct a full carbon assessment” of the company to “accurately quantify our carbon footprint and undertake specific measures to reduce our CO2 emissions”.
More generally within the manufacturing industry, it has been claimed that AM provides a more sustainable method of production when compared to traditional methods. According to French manufacturing service providerSculpteo’s“The State of 3D Printing” 2022 edition, AM has been shown to improve the environmental impact of key industry users (managers, engineers, designers). For instance, 41% of the respondents interviewed affirm that additive manufacturing helps companies meet their sustainability goals. Additionally, 61% of the manufacturers interviewed stated that additive technology allows them to meet their production needs. Ultimately, 84% of respondents claimed that they are optimistic about the potential of AM in the future.
Environmental sustainability within AM
During the 2022formnexttrade show,environmental sustainabilitywas certainly a key topic. For instance, at the show, industrial manufacturing firmSiemensdemonstrated how AM technology can be applied to reduce the carbon footprint of automotive grippers. By using itsProduct Carbon Footprint Calculator和NX for AM数字过程链，该公司已经发现能够将汽车处理机器人的抓地力质量减少64％。因此，该零件不仅价格便宜73％，而且二氧化碳足迹降低了82％。
3D printer manufacturerEOSalso demonstrated moves towards greater sustainability at the show, introducing two new eco-friendly materials:PA 2200碳还原和PA 1101 ClimateNeutral。PA 2200的开发具有更高效，更可持续的生产过程，其二氧化碳比以前基于汽油的材料少近45％。相似性，PA 1101是一种基于生物的粉末，其足迹比汽油聚合物较小。如此之多，材料已通过认证来验证其碳折叠式证书。
Elsewhere, theIndian Institute of Technology (IIT) Guwahatihas recently leveraged AM technology to construct a3D打印安全帖子使用M40级的可持续混凝土，其中包含工业废物，纤维和化学添加剂。IIT Guwahati助理教授机械部助理教授Biranchi Panda博士的说法，该建筑是作为G20 Summit计划的一部分生产的，利用了“可持续建筑材料”。熊猫还进一步强调了该项目如何“展示混凝土印刷技术的显着美学可能性”。
